Recommend reading for tutorial on electromagnetic

My degree is in electronics but at my university we do not have electromagnetics courses, just some general stuff when done general physics. I know electromagnetics is a very important subject in electronics so I want to study it, could you please recommend me a book about electromagnetics starting with the basics and gradually rising level ?

"Field and Wave Electromagnetics" 2nd ed. by David K. Cheng

I second that. It's a great introductory book.
